Study.com vs. Saylor

[Jenna.C]

I have never used any of these sites. I am a TESU student. For classes that both these sites offer, which would you recommend or would it depend on the class?

I know Saylor is  cheaper but I think you can finish Study.com a lot faster. And I think from what I understand, Study.com can be easier to understand. I could be wrong about that.
 
The General Ed classes I need to fulfill are the science class, Oral Communication, and the civic engagement requirement. 

Any information would be helpful! Thanks in advance!
